This invention includes the identification of a new mutation in the collagen type VI (COL6A1) gene, including a method for diagnosing and treating patients with this mutation. Collagen type VI-related dystrophies (COL6-RD) are devastating neuromuscular disorders that manifest with progressive generalized muscle weakness, contractures, and respiratory failure. Currently, no cure exists for COL6-RD. In addition, despite the effectiveness of current targeted genetic testing methods to detect many of the mutations causing COL6-RD, there are still a large number of patients presenting with clinical and biochemical features of COL6-RD, but without any identified mutations. Our novel identification includes a mutation in intron 11 of the COL6A1 gene that alters the splicing of the gene pre-mRNA and produces a mature alpha 1 (VI) chain mRNA that comprises an additional exon. We describe a method for diagnosing this mutation, as well as a method for specifically treating this mutation using exon-skipping technologies.
Commercial Applications
- Diagnosis services or kits to detect this mutation
- Oligomers or vectors for therapeutic clinical application
Competitive Advantages
Currently, no cure exists for COL6-RD. In addition, despite the effectiveness of current targeted genetic testing methods to detect most of the mutations causing COL6-RD, there is still a large number of patients presenting with clinical and biochemical features of COL6-RD, but for whom no mutations have been identified indicating that current methods of diagnosing and treating COL6-RD are insufficient. We found this particular mutation to be the single most common individual mutation in our COL6-RD cohort.
